This thesis describes the design, implementation and evaluation of an Intelligent Tutoring System (ITS) for Robust Division Skill. The design was based on literature of math instruction and a qualitative empirical study of division operations. The ITS has for interfaces, two for fluent division and two for making sense of division. The evaluation study focuses on the results of 4th grade students after working with the system in two conditions where different aspects of basic division learning are promoted. In one condition fluency was supported by having the student work on as many division problems as possible, and in the other condition “sense making” of division was supported, by encouraging reflection on the material. There is a trade-off between the number of problems solved, and the depth of understanding the problems solved. The students were tested on learning gains, fluency at division, and the transfer of division ability to new situations. The results show no significant learning gains. The most plausible explanations for this is that the students who participated in the experiment were already too proficient at division to benefit from further practice. Other possibilities are covered in the discussion.
